The 3-12x56 Meostar R1 has a 30mm maintube diameter, with its reticle placed in the rear focal plane (in front of the eyepiece) to maintain its virtual size throughout the entire magnification range. Targeting smaller game at longer distances is quite easy with the reticle location in the rear focall plane.
The 3-12x56 Meostar R1 is an extremely large and powerful optic for use in any ambient light conditions. It offers the magnification options useful for the open spaces of North American hunters, combined with an enormous oversized 56mm diameter objective lens to gather the light needed to produce stellar illumination upon the subject even at the maximum 12x power. The Meostar’s unique internal mechanism is designed for the highest mechanical resistance for consistent accuracy shot after shot.
